Workspace Health Monitoring Gadget

<![CDATA[]]>https://greenshoegarage.com/2020/10/learning-from-covid-19/<![CDATA[]]>

Goal

An open-source device that can monitor 8+ key environmental factors that affect people's perception of a healthy and productive workspace:


Temperature
Pressure
eCO2
Humidity
Brightness
Noise
TVOC
PM 2.5um


Code and hardware is a prototype, no guarentee of any sort is implied. Use at your own risk.

Functionality


Monitor 8 environmental factors


Central processing of all sensor data

Record the telemetry locally


24-hour rolling log
Store on microSD card

Display the telemetry locally


Display new data point every 3 seconds

Transmit telemetry to web-based cloud service


Send latest sensor readings every 10 minutes
